<P CLASS=para>
The <tt CLASS=literal>CheckboxGroup</tt> class provides 
the means to group multiple <tt CLASS=literal>Checkbox</tt> 
items into a mutual exclusion set, so that only one checkbox in the set 
has the value <tt CLASS=literal>true</tt> at any time. 
The checkbox with the value <tt CLASS=literal>true</tt> 
is the currently selected checkbox. Mutually exclusive checkboxes usually 
have a different appearance from regular checkboxes and are also called 
"radio buttons."
